Title: Retaining fill in a geotechnical structure
IPC: E02D17/20
Filed: 1980-06-25
Abstract: In order to provide a convenient way of forming a retainer construction for retaining fill in a geotechnical structure, one uses plastics material mesh which has spaced, longitudinal, orientated strands 1.

Title: Dispensing of beverages
IPC: B67D1/08
Filed: 1981-07-27
Abstract: The invention relates to apparatus for dispensing a beverage and including a flow detector having a bobbin or plunger located for sliding movement in a vertical cavity, a part of which forms part of a fluid flow passage. So that frothing of the fluid is not caused by fluid flow around the bobbin or plunger (54) during the dispensing of the beverage, at least a portion of the bobbin or plunger is raised to a position above a cross port (48) through which fluid flow from the vertical cavity (46) takes place. In addition, the arrangement is preferably such that, when there is no flow of fluid the bobbin or plunger (54) is located wholly within a lower part of the vertical cavity (46) connected with the flow passage but not forming part of it. <IMAGE>

Title: Polyalkenyl bis(succinic acids or anhydrides)
IPC: C10M129/95
Filed: 1981-08-05
Abstract: The invention provides a polyalkenyl bis-(succinic acid) or a polyalkenyl bis-(succinic anhydride) (PABSA) in which the polyalkenyl group is derived from a polyolefin having an Mn in the range from 500 to 2100 and compositions containing PABSA having the specified polyalkenyl group in combination with the corresponding mono-(succinic acid or anhydride). A particular feature of the process for producing PABSA by reaction of a polyolefin with maleic acid or maleic anhydride is the use of either a steam of gas, subatmospheric pressure or a nickel salt, e.g. nickel iodide, as catalyst. The products may be converted to ester or imide derivatives and used as dispersant additives in lubricating of compositions.

Patent GB-2115196-A (GB)
Title: Anti-theft systems
Inventor: TAYLOR ROBERT JOHN
IPC: B60R25/10
Filed: 1982-02-22
Abstract: To protect an automobile from unauthorised removal, a concealed switch or switches is located in the interior which allows one circuit to be "broken" when the owner vacates the automobile. The "broken" circuit cuts off the supply from the power source to the ignition coil and so renders the automobile immobile, at the same time permitting the starter to turn the engine. The resultant rotation of the fan belt on an automatic "cut-in unit" completes the "made" circuit and envokes the alarm system, which can be wired either for continuous or intermittent sounding of the horn or flashing of head or side lights and will not cease until the concealed switch is de-energised or the fused timer is envoked. <IMAGE>

Title: Process for the fluid catalytic cracking of a hydrocarbon feedstock
Inventor: STORDALEN ROLF MARTIN
IPC: C10G11/18
Filed: 1982-06-21
Abstract: In a process for the fluid catalytic racking of a hydrocarbon feedstock in reactor system comprising an endothermic cracking zone (6, 7) and in exothermic regeneration zone (13), heat is exchanged between said zones not only by the circulation of catalyst (5, 6, 11), but also by passing the fresh feedstock (1) through heat exchange coils (16) in the regeneration zone (13) before contacting hot regenerated catalyst in a liftpot (4) and entering the reaction zone (6, 7). The temperature in the regeneration zone is thus kept below 725 DEG C, whereas the feedstock is preheated to at least 200 DEG C, preferably to 325-400 DEG C. Heavy and high metal-containing feedstocks may be processed in this way. <IMAGE>

Title: Detector
Inventor: MASON COLIN
IPC: G01V3/12
Filed: 1982-10-01
Abstract: A detector, primarily for detecting the placement of an explosive device in a zone of a building or vehicle, has a transmitting element 10 transmitting electromagnetic radiation and at least one receiving element 12, the elements being located in spaced relationship near to the zone to be protected so as to form a transducer. Control means monitor signals received at the transducer and are operable to actuate an alarm system when the electromagnetic field in the zone under protection is disturbed, for example by the placement of an explosive device. A number of such detectors can be coupled via an encoding network 40 to a common transmitter 42 radiating to a receiver external of the building zone or vehicle. The receiver decodes and displays the alarm information. <IMAGE>
